om .121.5% mr" mmaatwu mmm 2 ermee downward or toward the conveyor. Such guide is sufficiently raised or clearfroln the conveyor to allow a sheet or signature to pass thereunder, but as it bends an oncoming sheet into the guide or convever channel it aids the sheet in correctly landingy in place.

Gages are shown at 5 and at (i whirn are adjustable, as by clamp or nul so as to lit the sheet or signature The lateral or sido gages 6 have arms T, carrying lalcral separators tl. These lateral separators are earried by or ad 'usted with the side gages, and they can also e separately adjusted, living; held by screws 9, which can be loosened to allow shiftingr ol the separators. By having the separators suitably rounded or their contact-points l'ree from sharp portions or angles these separa tors Will not out or injure a sheet or signa-` ture, ,While at the same time forming a hold for succeeding leaves or sheets.

A signal is shown at 10 in torni of a lever pivoted at 11, Figs. 3 and Il, and is arranged to move or give Warning when its gripper either misses a sheet or signature or takes an excess. This pivot 11 is mounted in the up per frame part c' between two bars 26 and 41, fixed parallel to one another along the machine. This signal has two lugs or dogs 12 and 14, and on the wripperhrm 'i is a dog;1 15, which is formed Witili or carried hy a slide 16, movable on arm i. A pin-anthslot connection can hold the slide shit'tably to the arm, the in being shown at 1"?. This dogi Vis sliifte or. set by a lever 153, fulcrumetl at 19 and ivoted to the slide 16, as shown at 20. A ink 21 connects this lever 18 with an arm of the gripper or (Shown in form of a lever fulcrurned at 22.) 1When the grip per is holding a sheet or signature said grip per is o en a certain extent an( the linie 21,with ever 18 and slide 111, are in such position that lthe dogl 1.1 swings between the eignal-dogs 12 and 14, thus clearing both and leavin the signal unallected 1l', however,

the gripper has seized an excess of matter and 1s open to an excessive extent, the link 21 has pulled lever 1S so that the dog 15 will have been shifted and that on the swing of armi said dog is brought against the signal-- dog 1? and the sional is moved, whereby the operator or attendant is warned. if, on the other hand, the gripperhas seized too little or has failed to seize an thing, the `laws or griper being closed the link Z1 will have pushed ever 18 to shift dog 15 into position to swing against signal-dog 14. 'lhe signal is thus again actuated and is moveijl as Well when the ripper has knot seized enough Vor has faile to seize or is entirely shut, as when the gripper has taken an excess orv theg'rippen 431m/'s are too far separated or excessively open.

Itis noted that the arme of levor'ltl are unequal, the longer one bein? connected to dog 15 and the shorter one toalink 21. Also the link 21 connects with the end portion ot the longer arm of the gripper-janv". This arrangement van be varied, but has been found practical, as thereby the motion of lug 15 is much greater than the movement ot the ,gripN ping end of jau'f actuating said dog or lug 15. Even il the gripper is taking thin sheets or signatures and such gripper is not to an)vr great extent held open by a' grasped thin sheet, still lhedogr 15 will have been shifted sulliriently to clear dogr il or pass between the signal-dogs 1'2 and 14 to clear the samev The dogs 12 and 1J.; are adjustable on the signal; but by reason oi the excessive shift just explained relative to dog 15 the adjustment of dogs 1;! and 11 is facilitated or need not be made with excessive ninety to be ellectivc.

The signal 1() is shown with an arm 23, lo the outer or tree end ol whieh is secured a spring 24, fastened to a suitable point 35. lMillion the dog 15 starts the signal so as to move point Z3 past the deadwentor or past the line drawn through points 11 and 25, the

, spring 24 will give said signal motion to such an extent as to attract attention.

The sigu nal will thus give *what might be called e full stroke or make a iull movement. 'lhe signal is shown limited in its movement by the shalt h at one side and rod 26 at the other. The rod or bar 26 is fixed to the frame or side pieces ol2 vthe device and carries a screw or stop 27, which can .be adjusted so that as arm 'i brings sliding pin .23 to this stop 27 the pin .28 is caused to press on the u .per arm of the toggle connection 29 and to end or lex the toggle connection 2f) to the'position shown in Fig. 4 tor the movable gripenjaw j" to he snapped or closed to the niemeer or jawf by the spring 8l). The ,'aiv j" is shown east or 'fixed to arm i. As toe arm i swings toward the Sere-W or suitably-adjusted stop 31 the toggle is actuated or straightened to open the gripper or slicetwitlidrawing rneolmnism 7".V
